CoCreateInstance returns 0x80080005 from VS2008 ATL Service
Roscoe
I have a VS2005 attributed ATL Service that I am trying to migrate to VS2008
non-attributed ATL by creating a new project and moving the application code
over. The service contains a COM object that I obtain via a smart pointer
CreateInstance() call (VC++), or a "new someclass()" call (C#). The interface
is custom (IUnknown) and the proxy is registered correctly. Nothing too
advanced here. The VS2005 version works without a hitch. The VS2008 version
returns a 0x80080005 HRESULT
(CO_E_SERVER_EXEC_FAILURE) every time from both the C++ and C# client calls.
If I register the service as just a COM EXE I am able to obtain the object no
problem. The minute I register it as a service though, I always get the same
HRESULT error. I've tried everything I can imagine. I've opened up dcomcnfg
to just about everything. Ive tried running the service under my local
account. No luck. Something changed in VS2008. Any ideas?
The system event log shows:
The server {guid} did not register with DCOM within the required timeout.
C# returns:
Retrieving the COM class factory for component with CLSID {guid} failed due
to the following error: 80080005.
C++ basically reports that it is unable to create the object and returns
0x80080005 (very informative).

What are your DCOM settings? What is the identity of the service? Does the executable do any kind of GUI activity at all?
Roscoe
dcomcnfg:
Default Authentication Level: None
Default Impersonation Level: Impersonate
The service gets registered currently using default DCOM securities:
Default Launch Permission:
Administrators; Interactive; SYSTEM - all allowing local launch & activation
Default Access Permission:
SELF; SYSTEM - all allowing local Access
I'e tried adding NETWORK, INTERACTIVE, SERVICE, my account - same thing
Not sure what you are looking for on service indentity. Standard
non-attributed ATL service logging on to the Local System Account. As a test
I used the VS2008 ATL service wizard and the ATL Simple Object wizard to
create an out-of-the-box ATL service. One CoClass with an IUnknow interface.
All wizard produced. I get the same problem. Same DCOM settings and the
VS2005 service performs flawlessly. Don't register the VS2008 service as a
"\service", but only as a COM Exe and it works fine - this shows that the COM
plumbing is set up and working.
This service does not interact with the desktop.

I understand that when you tried to create an instance of the class from
your ATL COM service, you encountered the error 0x80080005.
If I have misunderstood, please let me know.
I once encountered this issue from a customer. He resolved this issue
finally by adding FORCEREMOVE to the ATL COM service .rgs file, from
something like:
HKCR
{
TestSvc.CTest.1 = s 'CTest Class'
{
CLSID = s
'{5D5DBB0A-EE2F-4AD2-BD52-E8A9F740EA33}'
}
TestSvc.CTest= s 'CTest Class'
{
CLSID = s
'{5D5DBB0A-EE2F-4AD2-BD52-E8A9F740EA33}'
CurVer = s ' TestSvc.CTest.1'
}
NoRemove CLSID
{
ForceRemove
{5D5DBB0A-EE2F-4AD2-BD52-E8A9F740EA33} = s 'CTest Class'
{
val AppID = s
'{D56EC23A-E95A-4C47-8483-1BE79E8929E9}'
'TypeLib' = s
'{4504FDBA-04E8-40CE-B94B-A12DECDF9AEC}'
ProgID = s 'TestSvc.CTest.1'
VersionIndependentProgID =
s 'TestSvc.CTest'
ForceRemove 'Programmable'
}
}
}
to the following:
HKCR
{
ForceRemove TestSvc.CTest.1 = s 'CTest Class'
{
CLSID = s
'{5D5DBB0A-EE2F-4AD2-BD52-E8A9F740EA33}'
}
ForceRemove TestSvc.CTest = s 'CTest Class'
{
CLSID = s
'{5D5DBB0A-EE2F-4AD2-BD52-E8A9F740EA33}'
CurVer = s 'TestSvc.CTest.1'
}
NoRemove CLSID
{
ForceRemove
{5D5DBB0A-EE2F-4AD2-BD52-E8A9F740EA33} = s 'CTest Class'
{
val AppID = s
'{D56EC23A-E95A-4C47-8483-1BE79E8929E9}'
'TypeLib' = s
'{4504FDBA-04E8-40CE-B94B-A12DECDF9AEC}'
ProgID = s 'TestSvc.CTest.1'
VersionIndependentProgID =
s 'TestSvc.CTest'
ForceRemove 'Programmable'
}
}
}
I recommend that you first try this method to see if it helps. If this
issue persists, is it possible for you to mail me
(changliw_at_microsoft_dot_com) a sample project so that I can reproduce
your issue and perform further research?
If you have any other questions or concerns, please feel free to let me
know. It is my pleasure to work with you for further research.
